2010–11 Australian region cyclone season
The 2010–11 Australian region cyclone season was a near average tropical cyclone season, with eleven tropical cyclones forming compared to an average of 12. The season began on 1 November 2010 and ended on 30 April 2011, although the first tropical cyclone formed on 28 October. The Australian region is defined as being to south of the equator, between the 90th meridian east and 160th meridian east. Tropical cyclones in this area are monitored by five Tropical Cyclone Warning Centres (TCWC's): Jakarta, Port Moresby, Perth, Darwin, and Brisbane, each of which have the power to name a tropical cyclone. The TCWC's in Perth, Darwin, and Brisbane are run by the Bureau of Meteorology, who designate significant tropical lows with a number and the U suffix. The Joint Typhoon Warning Center also issues unofficial warnings for the region, designating significant tropical cyclones with the "S" suffix when they form west of 135°E, and the "P" suffix when they form east of 135°E.
==Seasonal forecasts==
Ahead of the cyclone season, the Australian Bureau of Meteorology (BoM), the New Zealand National Institute of Water and Atmospheric Research (NIWA) and various other Pacific Meteorological services, all contributed towards the Island Climate Update tropical cyclone outlook that was released during October 2010. The outlook took into account the moderate-strong La Nina conditions that had been observed across the Pacific and analogue seasons that had La Nina conditions occurring during the season.〔 The outlook called for a normal or above average number of tropical cyclone occurring during the season, with nine to twelve named tropical cyclones, to occur between 135°E and 120°W compared to an average of nine.〔 At least three of the tropical cyclones were expected to become category 3 severe tropical cyclones, while one was expected to become a category 4 severe tropical cyclone.〔 In addition to contributing towards the Island Climate Update outlook, the BoM issued seven seasonal forecasts during October 2010, for the Australian region and the Southern Pacific with each forecast covering the whole tropical cyclone year.〔 Each forecast issued took into account the La Nina conditions that had developed over the region and were forecasted to persist during the season.〔
For the Australian region as a whole it was predicted that the season could be the most active season since 1983–84 and that between 20 - 22 tropical cyclones would either develop within or move into the basin compared to an average of 12 cyclones.〔 For the Western region between 90°E and 125°E, the BoM forecast that the area would see between 11 and 12 tropical cyclones compared to the average of 7, it was also noted that the region had a 93% chance of an above average cyclone season.〔 For the North-Western subregion between 105°E and 130°E, it was predicted that activity would be above average, with 5 tropical cyclones and a 67% chance of above average tropical cyclone activity.〔 TCWC Perth also noted that there was a likelihood of two tropical cyclones and a significant likelihood of at least one severe tropical cyclone impacting Western Australia. It was also noted that there was an increased chance of an early season cyclone and a system impacting Western Australia before Christmas 2010.〔 It was predicted that the Northern Territory between 125°E and 142.5°E had a 75% chance of an above average season, and that the first cyclone of the season over the Territory and the monsoon onset would be expected to be earlier than normal.〔 The Eastern region between 142.5°E and 160°E had a 87% chance of an above average season, with 7-8 tropical cyclones predicted for the region compared to an average of 6.〔 The BoM also issued forecasts for the Western Southern Pacific region, between 142.5°E and 165°E and the Eastern Southern Pacific region between 165°E and 120°W.〔 It was predicted that the Western Southern Pacific would have a 79% chance of having an above average season with 7-8 tropical cyclones occurring within the region, compared to an average of 5 tropical cyclones.〔 The Eastern Southern Pacific region was predicted to have a 33% chance of having an above average season and 5-6 tropical cyclones compared to an average of 7 tropical cyclones.〔
The Guy Carpenter Asia-Pacific Climate Impact Centre (GCACIC) at the City University of Hong Kong and the Tropical Storm Risk Consortium (TSR) at the University College London also issued seasonal forecasts for the region.〔〔http://www.tropicalstormrisk.com/docs/TSRAUSForecastMay2010.pdf〕
